ABSTRACT:
A method of modulating digital data to be used for transmitting or recording N-bit (e.g., 8-bit) data comprises a step of converting the input N-bit data into an M+K-bit data selected out of a group of 2.sup.M M+K-bit data according to a predetermined rule, the group of 2.sup.M M+K-bit data being obtained by adding a K-bit error correction checking symbol to M-bit (e.g., 9-bit) data (N<M). For demodulation, the M+K-bit data is subjected to an error correcting operation or an error detecting operation before it is demodulated into an N-bit data.
